MORGAN HILL -- A 70-year-old Salinas man has been arrested Friday morning on suspicion of harassing and annoying a teenage girl during an overnight bus ride from Los Angeles to San Jose, according to the Santa Clara County Sheriff's Office.

The man, Maximiliano Aguirre, was taken to the Santa Clara County Sheriff's Office, where he was eventually arrested on suspicion of felony lewd acts against a person under the age of 14 and misdemeanor sexual battery.

The girl was with family members and traveling on a Greyhound bus to the downtown San Jose station, Sgt. Jose Cardoza said.

During the trip, the man "kept harassing and annoying" the girl, Cardoza said. Several witnesses said the man kept looking at her and getting closer to her by making trips to an overhead compartment. Investigators also determined that he "inappropriately touched" the victim.

The girl's family notified the bus driver, who pulled over on northbound Highway 101 near Bernal Road Hill and called 911.

"It was an unsafe scene," Cardoza said.
